Another idea is to get an M50 manifold and swap it in at the same time. Upgrade and maintenance at the same time!
I got under the car today, and replacing the hose from underneath looks impossible. First, I can’t see where the hose is going because the starter is in the way, and second, I can’t get my hands in there.

I’ve started the process of intake removal. So far, I’ve removed the front airbox piece and both throttle bodies. I’m gonna search for some decent DIY guides on how to remove the main piece, and hopefully I’ll be able to get that off tomorrow. Which gaskets do I need to replace, just the two manifold gaskets (11611740069)? Looks like they’re $14.22 each on ECS...

This job looks like a walk in the park without a supercharger there. Enjoy it and consider yourself lucky. Good time to wrench!

I got the intake off yesterday. Are there parts that I should replace preventively? I知 replacing the four coolant hoses, the manifold gaskets, and throttle body gasket. I知 also cleaning the ICV. Someone suggested that I replace the CCV and the connection flange for the three heater core hoses...is that necessary?

Supercharger doesn't change the job one bit. It's not in the way.

I told you.

The hoses that connect to the block, YES, replace.
CCV and drain hose are a good idea while in there.

You're right but I remove because I hate not having enough access room. Especially the 4th hour wrenching.

I mean, I didn稚 doubt you..I knew it would suck lol. But I値l probably do a better job than most of the BMW shops in Houston ッ\_(ツ)_/ッ

Okay I値l order the two throttle body hoses and CCV as well. The two larger hoses up front have already been replaced. Please let me know if I missed anything.

Check the vanos oil line hose. It is fully exposed and easily accessed right now.

Never ask "what should I do while I'm in there?". The list ends up being just short of a full rebuild

Part number 11361705532? I was looking at that line, and it looked like it had been replaced somewhat recently. I don’t mind replacing it again so it can be documented.

Oh I know how it works. A few years ago, I was going in to install subframe reinforcement plates (~$120) on the E46 and ended up ordering around $2k worth of parts
